I doubt that has much to do with it.  The JVM needs memory of its own that is 
separate from (but in the same Windows process memory space) the heap allocated 
to the java program that it uses for internal purposes.  For example, when you 
load a class into the JVM (not instantiate), it will take up a certain amount 
of memory to keep track of that class, its definition, etc.  This is stored in 
the JVM's memory space, but not on the application's heap.  When you 
instantiate the class, the instance of the class will be stored on the heap.  
The more complex your application (the more classes you have), the more memory 
the JVM will have to set aside for housekeeping (keeping tracking of the class 
definitions, etc.), and the less you will have for your heap.  DevStudio 
(Eclipse IDE with BMC plugins) is a complex application, so I suspect that the 
complexity of the application is the primary limiting factor on how much heap 
you can allocate for the program rather than how much free memory is on the 
machine (especially when there is more free memory than the 2GB process limit). 
 Having a full GB of extra free memory above what your process can even consume 
isn't going to help much - it's not even going to affect it.

That kind of explains why you cannot raise it beyond the limit you said. If you 
want to use more than what you have set, try increasing your client memory. For 
eg. if you want your max memory around 2048 MB, make sure that just before 
launching DevStudio you have at least about 3400 MB of 'available free physical 
memory'. Which might mean you might have to use a client PC that has about 4 GB 
of 'Total Memory'

Mind you there is a difference between 'Total Available memory' and 'Total 
Available Free Memory'.

Not quite, I have about 2.5 GB of physical memory available before launching 
DevStudio

Let me sport a guess here.. your client where you are running your DevStudio 
client from has available physical memory of about 1.8 to 2.2 GB before you 
launch DevStudio with any setting above 1354 MB??

Actually the maximum memory setting that I can specify in my devstudio.ini is 
1354 MB:

-vmargs
-Xms64m
-Xmx1354m

This is really weird....

David, I cannot increase my maximum memory JRE setting for DevStudio past 1280 
MB.
Shouldn't I be able to increase it to 2048 MB? What is the maximum memory 
setting for DevStudio?

Thanks, Guillaume

In AR System 7.5.00, the timeout for the C and Java APIs was increased to 8 
hours.  That was to address the ARERR 93 that is received on large exports, 
which represents a timeout.  The issue below is stated as running out of 
memory, which sounds like a different issue.

Guillaume,

I have not tested it with DS.(DevStudio)

This issue has been discussed on ARSList (and reported to the vendor) multiple 
times across multiple version(AKA: years).

However, in previous Admin Tool version I think you will find that the problem 
is actually a client timeout at the C API layer. Basically the Application 
Server can not get the objects together in one big string fast enough to return 
to the client before the client decides that the server fell off the face of 
the planet.

And the last time I asked Tech support... there is no environment setting that 
you can set to adjust the timeout. So there is no known way to override the 
"reasonable" timeout when you know your doing something that will take a very 
long time to complete.


In the past an approach to workaround this is to use things like Driver, or an 
API program to loop over all of the objects and export them one at a time.

Maybe DS fixed that problem? ( But it does not sound like it to me.)


What is amazing to me is that BMC Tech Support considers the fact that you can 
not export all of the objects at one time to be a "performance problem" and it 
is "the customers implementation" that is the root cause of the condition. 
(AKA: They are not even willing to open a bug against the version/API. So they 
take no responsibility and have no interest in re-implementing anything to 
avoid the problem of "slow customer hardware". And I have yet to have anyone 
from the company confirm that they have hardware that can actually do the task 
either.)
